180deg More important are the preheat and soakzones and temp ramps. How to check: I used to do it as follows: use a TEST-PCB with fixed thermocouples and connect it to the mole. Print the profile on transparant paper. do it again e.g. each week and

Currently we hand-assemble all prototypes, usually quantities less than ten. I mentioned the 5 to 50 number because a client will occasionally request more than ten, which has been handled previously by using an outside contract manufacturer (we are

Hi, Thanks for the info! In the software can you add solder paste specs and heat sensitive components and see where the profile sits against these fast? Measurement is the easiest part I think, but what I thinks harder is good software to analyze th
